The diaper 1 in the state of FIG. 4 in which the absorbing portion 3 is formed in this way is folded along the transverse line BB with the absorbing portion 3 inside, and the front and rear waist regions 6 and 7 are joined in the joining region 4. When the diaper 1 of FIG. 1 is joined so as to be integrated, crotch regions on both sides of the absorbing portion 3 which are bisected to the left and right by the vertical center line AA are shown in FIGS. As shown in the drawing, it is bent inward of the absorbing portion 3 so as to be directed to the vertical center line AA. More specifically, the absorbing section 3 is folded inward so that the outer surfaces 24 of the core elements 21c and 21e (see FIG. 5) face each other, and the outer faces 24 of the core elements 21d and 21f face each other. At the same time, the inner surface 23 of the core element 21a faces the inner surface 23 of the core elements 21c and 21d, and the inner surface 23 of the core element 21b faces the inner surface 23 of the core elements 21e and 21f (see FIG. 4). It is bent along a pair of grooves 20s and a pair of grooves 20t which are first and second bending curves. Thus, a pair of folded portions 50 are formed in the absorbing portion 3. The rectangular absorbing portion 3 having a U-shape and bent along the grooves 20s and 20t is folded into a flat shape so that the inner surfaces of the absorbing portions 3 overlap each other. A fold curve is formed along the groove 20u positioned so that the material elements 21c and 21e overlap and the core material elements 21d and 21f overlap. The absorbing portion 3 thus bent is in a state in which the core material 21 does not exist at all or slightly exists in the grooves 20s, 20t, and 20u. Rigidity is lower than that, and it is easy to bend as shown in FIG. 2 using the grooves 20s, 20t, and 20u as guides.
[0020]
Absorbing section 3 forms abdominal absorption area 3a, which is a non-folding part, ahead of folding part 50, and forms back absorption area 3b, which is a non-folding part, behind folding part 50 (FIG. 1). 2, 4). In the absorbent part 3, the crotch region part in the ventral absorption range 3a, that is, the position portion 3c is forward movement of the legs of the diaper wearer between the pair of grooves 20s and line C ₁ -C ₁ 4, For example, the intersection angle α is increased and the opening angle γ between the dashed line S and the dashed line S is reduced so as not to hinder the movement of the legs when the wearer walks or when the legs are extended forward and sitting. Preferably, the opening angle γ is within the range of 60 to 110 degrees. Further, the absorber 3, the crotch region portions in the dorsal absorption range 3b, namely to allow the portion 3d located between the pair of grooves 20t and the line C ₂ -C ₂ covers wide buttocks of wearer's to, to increase the opening angle δ between the chain line T and the chain line T to reduce the crossing angle beta _1, preferably fit the δ opening angle in the range of 120 to 160 degrees. In this way, in the diaper 1, even if the absorbing portion 3 is formed in a rectangular shape as shown in FIG. On the side, the movement of the wearer's legs is not hindered, and on the back side, body fluid leakage from near the buttocks can be prevented.
[0021]
As apparent from FIGS. 2 and 3, the absorbent portion 3 of the diaper 1 has an inner pocket 30 a formed inside the folded portion 50, and an outer pocket between the side edge portion 8 a of the covering portion 2 and the absorbent portion 3. 30b are formed.
[0022]
When the baby wears the diaper 1 of the present invention, the mother puts his hand inside the edge of the waist opening 9 and widens the opening 9 so that the baby's leg is passed through the leg opening 11. In the diaper 1, the deformation of the diaper 1 that widens the opening 9 does not reach the absorbing portion 3 separate from the covering portion 2 in the crotch region 8 far away from the opening 9, and the leg opening 11 is widened. Even if the side edge portion 8a of the crotch region 8 moves, the absorbing portion 3 hardly moves because the side edge portion 26 of the absorbing portion 3 is not joined to the side edge portion 8a. Therefore, the shape of the folded part 50 of the absorbing part 3 does not collapse. The absorbing section 3 fills a portion of the core material 21 along the chain lines S, T, and U contained therein with a water-absorbing material, and locally pressurizes or heat-presses the material with an embossing roll or the like. May be made more rigid than the surrounding area, and may be bent in parallel with those parts. In addition, the absorbing portion 3 fills the portion along the dashed line U with the absorbent material, and forms the grooves 20 s and 20 t in the portion along the dashed lines S and T except for the absorbing material, and then forms the folded portion. 50 can also be formed. It is preferable that the absorbing portion 3 has a sharp fold line formed along the chain lines S and T, but a fold line along the chain line U is not necessarily sharp. is there.
[0023]
FIG. 6 is a view similar to FIG. 4 showing an example of the embodiment of the present invention. In this diaper 1, a second transverse line DD which is shifted by a distance F closer to the front waistline region 6 than a transverse line BB which bisects the length of the diaper 1 in FIG. Each pair of grooves 20s, 20t, 20u is formed on the basis of the reference. The distance F is preferably in the range from 10 to 50 mm. The transverse line DD extends straight from the base point N on the longitudinal center line AA toward each side edge portion 26. From the base point N, a pair of chain lines S is again formed in the front waist region 6. The chain line T extends in the direction of the rear waistline region 7, and the chain line U extends in the front waistline region direction 6 between the chain line S and the chain line T. The intersection angles between the respective dashed lines S, T, U and the transverse lines DD are α, β ₁ , and β ₂ . In such a diaper 1, since the folding portion 50 is formed closer to the front waist region 6 than in the example of FIG. 4, the intersection angle α between the transverse line DD and the chain line S is changed to the transverse line DD and the chain line. It can be the same as the intersection angle β ₁ with T or larger than the intersection angle β ₁ . Even if the intersection angle α and the intersection angle β ₁ are the same, the width of the absorbing portion 3 becomes narrower in front of the transverse line B-B that bisects the diaper 1 back and forth, so that the absorbent portion 3 moves forward of the leg of the diaper wearer. There is little hindrance to movement. Therefore, the intersection angle α can be made equal to the intersection angle β to be 10 to 30 degrees. However, also in this embodiment, when the intersection angle α is set to 35 to 60 degrees so as to reduce the opening angle γ, and the intersection angle β is set to 10 to 30 degrees so as to increase the opening angle δ, the diaper 1 There is less hindrance to movement. Also in the diaper 1, in the crotch region of the absorbing portion 3, a portion 3 c located between the line C ₁ -C ₁ and the pair of chain lines S in the front non-folding portion has a small spread, and spread of the portion 3d located between the line C ₂ -C ₂ and a pair of chain lines T among the folding portion is increased.
[0024]
FIG. 7 is a view similar to FIG. 4 showing another example of the embodiment of the present invention. In the absorbent portion 3 of the diaper 1, the chain lines S, T, U and the groove 20s are respectively taken from two points G and H on the transverse line BB which are equidistant in the left-right direction from the midpoint M of the transverse line BB. , 20t, and 20u extend toward the side edge portion 26. The absorbing portion 3 is bent in the grooves 20s, 20t, and 20u in the same manner as the diaper 1 of FIG. In the absorbing section 3, a portion L between the point G and the point H on the transverse line BB is a boundary line between the abdominal absorption region 3a and the back absorption region 3b. The portion L can have an appropriate length of 0 mm or more depending on the size of the diaper 1 so that the effective folded portion 50 is formed. When the length of the portion L is 0 mm, the two points G and H coincide with the middle point M and become the diaper 1 in FIG.
[0025]
According to the present invention, in addition to the diaper 1 illustrated in FIGS. 1 to 7, the width of the crotch region 8 in the covering portion 2 is the same as the width of the absorbing portion 3 in the state shown in FIG. It can be implemented smaller than the width. In this case, the absorbing section 3 covers the outer surface 24 of the core 21 with a liquid-impermeable sheet, and can join the liquid-impermeable sheet to the covering section 2. In the joining, the absorbing portion 3 can be joined to the front waist region 6 and the rear waist region 7 of the covering portion 2 and not joined to the crotch region 8. In the diaper 1 thus joined, the covering portion 2 can be replaced with one having only the front waist region 6 and the rear waist region 7 by cutting off the crotch region 8. The present invention described by taking the diaper 1 as an example can be implemented in a wearing article such as training pants, pants for incontinent patients, and sanitary pants.
